Ordered my replacement radio for a work truck I had just bought, in which the on/off button was broke. When I received the radio none of the local AM channels came in, but all the FM did. Called Factory Radio and they promptly offered to exchange it. When the new radio arrived I had the same issue. It turns out the antenna is the problem. I am sure the first radio was fine and would have worked as expected. Both radios were packaged better then I expected, which from my experience is usually not the case. Hats off to Factory Radio and all the people there, Thanks!
